摘要：
PURPOSE: A positron emission tomography(PET)-magnetic resonance imaging(MRI) convergence system is provided to improve the quality of converged image by blocking the mutual influence caused by MRI and PET, and to suggest a detachable structure for using a PET detector separately, thereby obtaining a PET-MRI converged image of high quality and operation efficiency.CONSTITUTION: A PET-MRI convergence system includes an MRI system(201) for MRI image and a PET detector(202) for PET scan. The PET-MRI convergence system comprises a magnet bore(210) a gradient coil(211) which generates a gradient magnetic field a body coil(212) which emits an RF pulse signal to an examinee an MRI RF receiver coil(213) which receives MRI data a first through-hole(214) a second through-hole(215) a PET detector(221) which detects PET data emitted from an examinee a carrier(230) which carries an examinee a RF shielding(222) which blocks the RF signal emitted from the MRI RF coil and a carrier driving unit(231).COPYRIGHT KIPO 2013본 발명은 융합 시스템에 관한 것으로, 더욱 상세하게는 PET(Positron Emission Tomography)-MRI(Magnetic Resonance Imaging) 융합 시스템에 관한 것이다.본 발명의 실시 예에 따른 PET-MRI 융합 시스템은, 원통형으로서 외벽과 내벽을 갖는 마그네트 보어(Magnet bore) 상기 마그네트 보어의 내벽에 인접하여 설치된 경사 코일(Gradient Coil) 상기 경사 코일의 내벽에 인접하여 설치되고, RF 펄스신호를 방출하고, 상기 RF 펄스신호에 대응하는 MRI 데이터를 검출하는 MRI RF 코일 및 PET 데이터를 검출하며 상기 PET-MRI 시스템에서 탈부착이 가능한 PET 검출기를 포함한다.
